Research:Higlights of „Hot Topics“
Thermal Hydraulic Safety Analyses• Validation & uncertainty of system codes & CFD • Turbulent flows DNS, LES (H20, Na; THINS)• Fast transients in two-phase flows (WAHALoads)• Two-phase flows with two-fluid models and interface tracking
schemes (NURESAFE)• Transitional two phase flows• Modeling of flows in complex geometries (fuel bundles, multiple
jets)
Severe Accidents• Interaction between containment safety systems and atmosphere
(SARNET)• Fuel-coolant interactions (H20, Na; SARNET)

Research:Higlights of „Hot Topics“
Ageing and Integrity• Multiscale models of intergranular/intragranular damage• Models of cracks in complex conditions (dissimilar welds, MULTIMETAL)
Probabilistic Safety Assessment• Uncertainty and time dependent (ageing) PSA• Impact of grid reliability and power system optimisation, External hazards
Multiphysics• Models of thermal fatigue (computational fluid & structural mechanics)• Coupling of neutronics & thermal hydraulics• Integration of deterministic and probabilistic safety analyses
Focus on numerical models and simulations
Experimental: cooperations and EU infrastructure access

The Framework
The Goal:
Nuclear energy to prosper in highly demanding and fast evolving (European) markets.
The Prerequisites:
Nuclear energy is safe (and perceived so by the society!)
Nuclear energy is competitive (all stakeholders!)
REMOO 2013, Belgrade, Serbia

Safe and perceived so by the society!
What?
• Better technologies and operating procedures
• Better trained technical staff
• Better understanding of risks, in relation to societal expectations
• Better risk prevention
• Better accident mitigation procedures and resources
• Better public information

Safe and perceived so by the society!
How?
• careful operating experience analysis: to learn from the past and identify precursor events
• research programmes: new knowledge for new approaches and solutions
• operator independent and science based cross-cutting expertise in support to safety authorities: to enable the regulatory process beyond static conformity, towards requirements for state of the art safety, security and radiation protection improvement
• Upgraded knowledge management and training resources

Competitive (all stakeholders)
Competitive (and safe) for decades, a century:
Anticipate, generate and adapt to huge technical progress
Anticipate, generate and adapt to huge changes in the society
Vigorous strategy for longtern promotion of:
Research
(Higher) Education
Safety culture

The Framework
The Goal:Nuclear energy to prosper in highly demanding and fast evolving (European) markets.
The Prerequisites:Nuclear energy is safe and perceived so by the society!
Nuclear energy is competitive (all stakeholders!)
The Challenges:All stakeholders to work closely together and support each other to create and implement the necessary knowledge and knowhow. Longterm effort!
A lot of money and top level experts!

Reflections from REMOO 2012
Education and Safety Culture
Should post-Fukushima investments go beyond Improved Technology and include Education and Safety Culture?
Research and Safety Culture
Should sustainable developments of Safety and Safety Culture rely on Research (Best Available science)?
Promotion and Support
Should the nuclear industry publicly promote and support the Research and Education?

Summary
Nuclear energy could prosper in highly demanding and
fast evolving (European) markets, if:
• Safe AND perceived so by the society!
• Competitive (long term, all stakeholders)
All stakeholders to work closely together and support
each other to create and implement the necessary
knowledge and knowhow.
• A long term strategy and vigorous activity!
• Requires (a lot of) money and top level experts!
